In my menu's navigation area I've placed a drop down menu. Since the last update there was automatically placed a drop-down icon, yet it's just a ugly square. On Firefox i've found out that it resembles the Unicode f107. which is the usual code for a 'normal' dropdown icon.
I couldn't find a way to edit this (broken) icon into another. Is there a way to change this icon? if so, where could I do that.
I've also found out that I can’t access the files of my template located at /templates/shaper_helixultimate. When I try to open for example the CSS file, I get the error "There has been a mistake. 3 arguments are required, 2 given".
Is there a way to fix this?
